Restore / Default Style?

[Bunni U]

What is the best way to reset the styles back to the single default that comes preinstalled?

I had an admin go and make changes which subsequently screwed up all the styles we have installed and subsequent styles. Ive tried reverting the styles: templates and vars. However it seems the recent vb patch has prevent a full reversion. Ive spend hours trying to figure out what was done. However it would be much easier if i could just wipe the styles we have now and go back to the default with well.. default settings.

Whats the best way to go about this? Dump the style related tables and run the relating sql from the install files?

Any and all help will be greatly appreciated!
